Description
Technical field
The present invention relates to a kind of deduster, be specifically related to the built-in pulse bag type dust collector of a kind of blower fan.
Background technology
Along with the development of modern industry, dust is day by day serious on the impact that the pollution of environment and the mankind's health causes, and administers dust pollution, purifies the mankind's living environment, has become compatriots' common recognition.Deduster is the equipment that dust is separated from flue gas.Deduster has number of different types, and wherein pulse bag type dust collector since the fifties comes out, through being widely used both at home and abroad, has been updated, and is obtaining very great development aspect the purification dusty gas.
Chinese invention patent CN102698517A discloses a kind of little pulse bag type dust collector of noise that moves, its structure as shown in Figure 1, comprise dust-removing box 1 and outside supporting blower fan apparatus, described blower fan apparatus comprises tube connector 2, centrifugal blower 3 and exhaust duct, described tube connector 2 is connected with dust-removing box 1, described tube connector 2 is connected by centrifuge 3 with exhaust duct, is provided with silencing means in described exhaust duct, described dust-removing box 1 comprises the upper box that sets gradually up and down, middle casing and lower box, described upper box is provided with air outlet, described middle casing is provided with air inlet, and should be provided with the filter bag that the upper end is communicated with upper box in middle casing, the dedusting path profile of dusty gas in dust-removing box as shown in Figure 2, dust-cleaning principle is: during the equipment normal operation, dusty gas enters ash bucket by air inlet, rapid expansion due to gas volume, the thicker grit of a part is subjected to the reasons such as inertia or natural subsidence to fall into ash bucket, all the other most of grits rise with air-flow and enter a bag chamber, after filter bag filters, grit is trapped in the outside of filter bag, purified gas enters upper box by filter bag inside, again by the valve plate hole, air outlet enters tube connector, then, the Purge gas that enters tube connector enters atmosphere by exhaust duct under the effect of centrifugal blower, thereby reaches the purpose of dedusting.
Along with constantly carrying out of filtering, dust remover resistance also rises thereupon, and when resistance reached certain value, the deashing controller sent the deashing order, at first will promote valve plate and close, and cuts off filtered airflow; Then the deashing controller sends signal to impulse electromagnetic valve, and sending in bag to air-flow as the high-pressure reverse of deashing, the rapid bulging of filter bag, and produce strong shake causes the dust in the filter bag outside to be shaken off, and reaches the purpose of deashing along with pulse valve.Because equipment is divided into several casees districts, so said process is undertaken by case, a case district is when deashing, and all the other casees districts has guaranteed the continuous normal operation of equipment still in normal operation.Because the ash-clearing technology of pulse bag type dust collector is advanced, air cloth ratio increases substantially, and the air quantity of processing is large, the advantages such as floor space is little, purification efficiency is high, reliable operation therefore have, and is high-effective dust-removing equipment a kind of maturation, fairly perfect.
But there is following shortcoming in this pulse bag type dust collector: (1) centrifugal blower is located at the outside of dust-removing box, and the blower fan running can produce noise to working environment; (2) air inlet of centrifugal blower is connected with dust-removing box by tube connector, and the resistance that the bending place of tube connector can be larger to γ-ray emission is unfavorable for gas communication; (3) the air outlet place of centrifugal blower need to enter atmosphere with gas by means of exhaust duct, and the use of tube connector and exhaust duct causes production cost and mounting cost high; (4) the unit pulse bag type dust collector is the needs that satisfy various working, and it should be equipped with high-power centrifugal blower, can not regulate the power output of centrifugal blower according to the number of devices of opening in workshop, causes the very large wasting of resources.
For addressing the above problem, need provide that a kind of noise is little, cost is low, the pulse bag type dust collector of energy conservation.
